Qi Lin rested for five or six hours, and Ivan walked into the room with the two mutants.

"It's time to go, this time is the time when mutant creatures are infested with the lowest frequency."

……

……

The warehouse in Ivan's mouth is located at the foot of the valley north of Nerozsk, and at the entrance is a cave similar to an anti-aircraft tunnel, and there are two signs in Russian hanging on the outside, telling Qi Lin that this tunnel is a three-defense fortification built by the former Soviet Union during the Cold War.

This fortification was also built in preparation for nuclear war, but it fell into disrepair and was abandoned.

It's just that, according to Ivan, after the first signs of the Third World War appeared, the Russian government did not open and repair this old three-defense fortification, but built a new shelter near Nerozsk, that is, the "Far East E04 Shelter" where Ivan and his family were.

Of course, the newly built shelter must be more reliable than the tunnels dug nearly 100 years ago, and before the shelter was contaminated by radiation, the Far East E04 shelter was also connected to the underground shelter network in the Russian Far East, which can effectively guarantee both materials and information.

But the problem is that the Far East E04 shelter is only a small shelter, completely unable to accommodate the entire Nerozsk residents and refugees from the surrounding areas, after the shelter is full, people who could not squeeze in think of this Cold War period of the three fortifications, but at this time, they desperately found that the entrance to this fortification has been sealed by the government with a heavy steel gate, and it cannot be opened at all.

"So what's going on?" Qi Lin pointed to the black hole of the fortifications, except for the half-human-high weeds around him, he didn't see any trace of the big iron gate at all.

"Do you know about this bug?" Ivan rummaged around the ground for a while, then picked up a gray-white insect remains.

The insect looks similar to a termite from the outside, but it has subtle dark green lines on its body, and even though the insect has been dead for a long time, those dark green lines are still emitting a faint glow - this look is the mutation caused by the radiation.

"Gold-eating ants, these little insects feed on metal, and their saliva contains a strong acid that can corrode metal into a state where they can swallow. The big iron gate was eaten alive by a colony of gold-eating ants that flew here from somewhere else. ”

"What about these gold-eating ants? After eating the iron gate and flying away? ”

"We originally thought so, but there was no trace of corrosion and gnawing on other metal objects in Nerozsk, and later during one of our explorations, we found that this group of insects was attracted by the radiation in the depths of the fortifications, flew in, and finally all died under the strong radiation."

Many of the mutated creatures of insects are extremely tropic to radiation, just like Jett's taste is attractive to addicts, although they can't withstand such a high intensity of radiation at all, they will still act like moths to fire.

At the mouth of the tunnel, there is a simple hand-pushed rail car made of iron sheets, which uses pure human labor, as long as you push a handful, and then constantly press a lever located at the rear of the car by hand, the whole car can continue to move forward.

Beneath the car, a rusty track stretches from the entrance to the depths of the tunnel.

Although in Qi Lin's eyes, the darkness in the tunnel did not exist at all, but at about two hundred meters, the tunnel turned a corner, so he could not see the deeper scene.

"We're walking, it's so noisy that it attracts a lot of mutated creatures living in the tunnel, and the track in between is broken in several places." Ivan said, gesturing to the railcar.

"Hmm." Qi Lin nodded, and then Ivan waved his hand, and the two mutants who were short and thin, and had quick movements, took the lead and walked in with silent steps, and after the two mutants entered more than twenty meters, the others followed one after another.

According to Ivan's instructions, try not to make a sound when you enter the tunnel, and never shoot, in the tunnel, the echo of the gunfire will be heard far, far away.

The tunnel is wide enough for three heavy trucks to stand side by side, and at the top of the tunnel is a thick metal pipe, and next to the pipes, bundles of cables with aging and cracked rubber skins.

The terrain of this tripartite fortification inside the mountain is intricate, like a labyrinth, but due to the first few explorations of the mutants, there will be white lime markings on the wall every time they reach the fork in the road, so there is no need to worry about making a mistake.

As everyone gradually deepened, Qi Lin obviously felt that the radiation concentration in his surroundings was high, although this feeling made him very comfortable, but the steps of the mutants around him began to become heavy.

After turning a fork in the road and advancing nearly a kilometer, Ivan finally signaled everyone to stop.

"It's almost close to our limit here, and there's no fork in the road, and the source of the radiation is in the deepest part of the tunnel." Ivan whispered, and then handed a backpack to Qi Lin.

"This is a night vision camera, I need you to take a picture of the inside of the warehouse for me, in addition, according to the information we have exchanged for death in our previous explorations, the door of the warehouse has been destroyed, so you don't have to worry about entering the warehouse, but be aware that there may be mutated creatures in the warehouse that adapt to high-intensity radiation."

"You've got four hours and we'll pick you up at the last fork in the road, but if you don't get out within four hours, we'll leave — understand, four hours in this environment is already very difficult for us."

As Ivan spoke, he raised his hand to wipe away a wisp of black blood that had spilled from under his nostrils, and in addition to him, most of the other mutants also had some uncomfortable reactions, and several of them were weaker, and they were constantly twitching and trembling, and they needed the support of the people around them to barely stand.

"I see, but if I encounter a monster that is too powerful, I will give up this mission."

Ivan nodded, glanced at Qi Lin, and then turned around with the mutant and walked out, leaving Qi Lin here alone.

It wasn't until the last mutant disappeared around the corner that Qi Lin took a deep breath of turbid air with a strong rust smell and fishy stench - although the environment in the tunnel could be described as extremely harsh, but for Qi Lin, who had absorbed the heart of the Black Forest, it was as comfortable as a fish in water, and his whole body was full of overflowing energy.
